Yes. I'm curious about it.
As I posted before, he will attend "Olympic Concert 2013" held by JOC this afternoon. So he is officially in Japan now.
The concert will be aired by NHK digital TV on June 30 from 4:30pm to 5:30pm. According to this page we will see and hear him talk about his thoughts on Olympics there.
We might get to see him again as NHK will air a clip from the Olympic Concert today on its sports news program, Sunday Sports at 22:05-22:30.
